The part of XML document that we will use for the following examples is:
..........
<items>
<item>
<productID description="Product_1">CO11</productID>
<quantity>5</quantity>
<price>1.23</price>
<currency>USD</currency>
</item>
<item>
<productID description="Product_2">CO12</productID>
<quantity>7</quantity>
<price>2.34</price>
<currency>USD</currency>
</item>
<item>
<productID description="Product_3">CO13</productID>
<quantity>9</quantity>
<price>3.45</price>
<currency>USD</currency>
</item>
</items>
<total>53.58</total>
..........
1. sum(Data/instanceData/POdocument/items/item/price)
Result: 7.02
2. //item[2]/price * //item[2]/quantity
Result: 16.38
3. round(//items/item[1]/price)
Result: 1
4. floor(//items/item[1]/price)
Result: 1
5. ceiling(//items/item[1]/price)
Result: 2
6. (//items/item[1]/price*//items/item[1]/quantity) + (//items/item[2]/price*//items/item[2]/quantity) + (//items/item[3]/price*//items/item[3]/quantity)
Result: 53.58
7. (//items/item[1]/price*//items/item[1]/quantity) + (//items/item[2]/price*//items/item[2]/quantity) + (//items/item[3]/price*//items/item[3]/quantity) = //total
Result: true
